Concepts and uses
Most of the pages contained in the Metalith™ website show the Metalith blast barriers and crash barriers configured in bare metal finishes. This configuration displays engineered containment structure for the ballast material providing the excellent blast mitigation and anti-ram protection.
However, for many of the critical infrastructure applications the Metalith barrier systems can protect, it needs to present a more pleasing and aesthetic appearance. The Metalith walls can hold a wide variety of architecturally specified finishes or looks. These can be as unique or as functional as an architect or engineering firm specifies. Three examples include the:
Architects were recently asked to develop a number of conceptual exteriors that could be readily connected to the Metalith barrier containment structures. Some of the exterior concepts were unique, some were functional, and some were designed to be inexpensive. What can be attached to the Metalith barrier system can be as distinctive or as practical as an architect or engineering firm specifies. Some examples include the:
There are a wide array of exterior finishes that can be specified for the Metalith and they typically can be reasonably accommodated. An example is the acrylic polymer brick-like finish shown in the figure to the right completely altering the "no-nonsense" appearance of the Metalith sheet metal facing.
Another unique design is a Metalith barrier encased in a pre-cast concrete panel that is faced with a metal panel cut in a geometric pattern. For water protection and aesthetic looks the top is covered by a rigid polyurethane foam cap an highlighted with an occasional polyurethane post top.
The Infrastructure Defense Technologies' Metalith perimeter security earth filled protective barrier system may lend itself to other uses. Basic CMI wall modules may be combined to produce any length of wall or cover the entire perimeter of even a large facility, providing either or both anti-ram and blast wall protection as shown in the illustration below.
This configuration shows a basic Metalith barrier system offering protection from an inadvertent or deliberate attempt to crash through the walls or blast mitigation protection from a vehicle borne improvised explosive device (VBIED) that could be detonated with little standoff in this rendering.
For applications where the engineering or architectural specifications may require a wall height higher than recommended, although 25 to 40 foot wall heights are possible, the addition of a Kevlar® blast or obscuration shield can easily extend the height of wall up to 60 feet above the corrugated metal portion. This wall height would make the wall nearly impossible for any intruder to climb.
The basic Metalith protective barriers may be easily enhanced with many types of surface coatings or false exteriors to provide a stone or brick appearance, stucco, or a smooth or rough surface in various colors all enhancing the basic anti-blast, anti-crash barrier's appearance.
The Metalith perimeter security barriers can be augmented with the addition of a transparent obscuration shield providing a protective and visual screening height of up to 60 feet for this application, a satellite downlink station.
If a visual screening effect is not enough, the Metalith anti-blast and anti-ram walls can be modified to produce a "Tall Wall" (60 feet in height as shown in the diagram to the left) used to completely obscure the satellite downlink site as shown.
The configuration below incorporates poles mounted inside the Metalith earth or sand ballast to support the upper barrier material. It shows how the vertical supports penetrate into the Metalith roof and fill ballast to provide support for the "Tall Wall" configuration.
The architect or engineer may specify the basic Metalith barriers with our Anti-Climb optional panels making the barrier much more difficult to scale and providing an excellent deterrent to an average intruder. Adding a barbed wire or electrical wire deterrent increases the likelihood that most intruders will not try to gain access while still providing excellent blast mitigation and anti-ram vehicle protection.
A concern at home as well as for many locations overseas is the protection of natural gas and crude and refined oil pipelines plus the supporting pumping station infrastructure. Oil pipelines are usually the only feasible way to transport significant volumes by land over long distances. The diagram shown below illustrates a basic unprotected pipeline.
Below is a basic, baseline, method showing how the Metalith panels can be used as a pipeline protection system. However, this configuration does not provide easy access for service or repair.
Another configuration designed for the Metalith use as a pipeline protective system uses a hollowed version with two vertical Metalith mini-walls supporting a capstone section, all filled with sand, earth, or other ballast material. This configuration allows direct access to the pipeline at designed intervals for pipeline maintenance crews.
The Metalith earth filled protective barrier system is designed to protect personnel and critical infrastructure facilities from the blast effects of a high order detonation, shield them from incursions from vehicles crashing into walls attempting to break through or just by accident, deter simple manual intrusions, and delay those making armed incursions. The interior doesn't change much to provide these benefits.
The exterior or finish is only limited by the imagination of designers, architects and end-users.
